VERDICT
US-IP Google & Microsoft Email Infrastructure - inboxkit.com
Depends. Buy it if you run high-volume cold outreach and need many US-IP Google/Microsoft mailboxes provisioned fast. Skip it for ordinary business email or low-volume sending — plain Google Workspace is simpler and cheaper.
Medium. Based on 24 public sources; most snippets are truncated and several reviews are competitor-published, which tempers confidence.
